(B) The Cannizzaro reaction involves the nucleophilic attack of $OH^{-}$ on the carbonyl carbon,followed by the intermolecular transfer of a hydride ion $({H^{-}})$ from the tetrahedral intermediate to another molecule of the aldehyde. Thus,the key step is the shift of a hydride ion $({H^{-}})$. Therefore,the correct option is $(B)$.
